Abstract
The utility model relates to a laser-white-light two-used nasopharyngoscope which is in particular suitable for optical medical device for diagnosis of early rhinopharynx and cancer of larynx. The utility model is characterized in that the white-light system is provided with a cube prism for the switch of the laser and the white-light and a laser transmission system consisting of a laser light source, a filter, a coupling lens, an optical fiber and a short-focus lens. The same light path coupling and real-time switch of white-light system and the laser system are realized through the prism. The laser can adopt argon ion laser, helium cadmium laser, krypton ion laser and nitrogen molecular laser. The laser sent by the laser irradiates the tested tissue through the optical train and realize the aim of laser and fluorescence diagnosis. The white-light source also irradiates the tested tissue through a light beam and the cube prism and then through the optical fiber light beam of the rhinopharynx endoscope to realize real-time alternation or simultaneous utilization of laser-white-light and achieve the functions of diagnosis and position. The device has simple structure, convenient utilization, high precision of fluorescence diagnosis and accurate position of white light.
Description
This utility model relates to the dual-purpose nasopharyngolarygnoscope of a kind of novel laser-white light, is specially adapted to the optics medical device that adopts MAK BY LASER EXCITED FLUORESCENCE that early stage nasopharynx laryngeal carcinoma is diagnosed in the laser medicine application.
Nasopharyngeal carcinoma and laryngeal carcinoma are one of pertinacious diseases of incidence harm humans health and lives, account for 18% of China's tumor incidence.80% nasopharynx laryngeal carcinoma case occurs in each province, China south in the world, and its sickness rate is high.The early stage non-evident sympton of patient, very difficult the discovery.For a long time, the white light nasopharyngolarygnoscope is widely used clinically as a kind of main inspection and the positioning means of nasopharyngeal carcinoma and laryngeal carcinoma.Yet because the white light nasopharyngolarygnoscope can only use white light list kind light source.During diagnosis, the doctor only can rely on naked eyes, in conjunction with individual's experience, the change of nasopharynx larynx population structure and form is judged and identification.Become and minute lesion for mucosa mo(u)ld bottom half carninomatosis, its rate of examining out is extremely low, and the most applications biopsy of taking a sample for several times also is difficult to confirm, causes and fails to pinpoint a disease in diagnosis or mistaken diagnosis.Utilize " MAK BY LASER EXCITED FLUORESCENCE " of laser (as argon laser),, be applied to the diagnosis of early stage carcinoma as a kind of " optical biopsy " technology because of it has Non-Destructive Testing, the high outstanding advantage of sensitivity as light source.Existing medical and clinical nasopharyngolarygnoscope only provides white light source, in order to implement the laser-induced fluorescence (LIF) inspection, must be designed for the laser optical path of transmission exciting light.
Task of the present utility model just provides a kind of Laser Transmission optical system of introducing in former white light light path system, constitute novel laser---the dual-purpose nasopharyngolarygnoscope of white light.This mirror had both kept original white light systems and had diagnosed accordingly and positioning function, can increase or change light source (as laser) as required again, mucosa mo(u)ld bottom half carninomatosis is become and minute lesion is implemented fluoroscopy, and then judge and discern the early stage nasopharyngeal carcinoma and the novel nasopharyngolarygnoscope of laryngalgia.
Task of the present utility model is achieved in that the laser of laser instrument output, through the Laser Transmission optical system, that is: behind optical filter and the coupled lens, by silicon fiber with Laser Transmission to short focal length lens, be totally reflected to the biography light fibre bundle of nasopharynx endoscope through block prism, and via pass the light fibre bundle with Laser Transmission to tested tissue.Be provided with the quickly responding to switch that the laser white light switches usefulness mutually in the block prism, as required, real-time change-over switch, change the light source kind of the tested tissue of irradiation, or be single light source, as white light or laser, or be multiple light courcess, shine simultaneously as laser and two kinds of light of white light, thereby realize the fluorescence diagnosis and the white light of the tested tissue of patient's nasopharynx part are located.
Below with reference to accompanying drawing this utility model is described in further detail.
Accompanying drawing one is the longitudinal sectional drawing of a kind of concrete structure of this utility model.
Shown in accompanying drawing one, the biography light fibre bundle (16) of laser instrument (10), optical filter (11), coupled lens (12), optical fibers (13), short focal length lens (14), block prism (15), endoscope constitutes the Laser Transmission optical system.The laser of laser instrument (10) output, after filtration behind mating plate (11) and the coupled lens (12), by optical fibers (13) Laser Transmission is arrived short focal length lens (14), be totally reflected to the biography light fibre bundle (16) of nasopharynx endoscope through block prism (15), by pass light fibre bundle (16) with Laser Transmission to tested tissue.White light source [20] arrives tested tissue through the optical fiber biography light beam [16] that condenser lens [19], heat-protecting glass [18], extraneous biography light beam [17] and block prism [15] are injected into nasopharyngolarygnoscope.Nasopharyngolarygnoscope object lens [2] are collected from the fluorescence of tested tissue and are diffused; through cover glass [1], combined objective [2]; imaging goes up at the field stop [3] of eyepiece [4], again after eyepiece [4] and grating filter [5], by convertible lens [6] imaging on the time of casting image intensifier [7] pole-face.Last human eye is being observed fluorescent image or the white light image after the process enhancing amplification on casting image intensifier [7] fluorescent screen on eyepiece [8] emergent pupil [9] position, thereby realizes fluorescence diagnosis and white light location to the tested tissue of patient's nasopharynx part.Laser instrument (10) can adopt various low-power lasers, as argon ion laser, helium cadmium laser, krypton ion laser, nitrogen molecular laser etc.Then Wavelength of Laser is different to design corresponding anti-reflection film to short focal length lens (14) according to using, and can adopt shapes such as plano-convex thick lens, globe lens, GRIN Lens.The setting of block prism (15) has realized the real-time conversion of laser, white light.
The utlity model has simple in structure, good reliability, coupling efficiency height, instrument volume be little, face The advantages such as bed is easy to use. Simultaneously, by the Laser Transmission optical system, the laser of realization optical system-The function that two kinds of light sources of white light are used alternatingly can be flexibly, provide the white light inspection for the patient easily With highly sensitive fluorescence diagnosis.
